IMPROVED CAR-COUPLING.

Specification forming part of Letters Patent No. 50,152, dated September 26, 1865.

To all whom it may concern.'

Be it known that I, LORING MOODY, of Malden, in the county of Middlesex and State of Massachusetts, have invented an Improved Bailwayar Coupling; and I do hereby deolare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view, Fig. 2 a side elevation, and Fig. 3 a longitudinal section, of it.

In the said drawings, A denotes a bunterbar of a railwa-y-carriage, such bar being provided with a link-chamber or receiving-recess, a, having a Haring or trumpet mouth, b.

A lever, B, formed as shown in the drawings, is arranged within the buuter-bar A, and is supported not only by the front part being made to rest on the top of the surface of the bunter-bar, but by means ot' a fulcrum-pin, c, which goes through the bar transversely ot' it, and also through an elongated slot, d, made through the lever near its rear`end, and arranged therein in manner as represented in Fig. 3. The lever is disposed in a slot, c, formed vertically through the bunter, and projects from the said slot, and has. or may have a pring,j`, to force its longer arm downupon its seat, the said spring being fastened to the top of the bunterbar, and arranged as exhibited in Figs. 1, 2, and 3.

There is suspended from the lever B a pendulous pin, O, which extends down through the vertical passage or slote and the mouth of.

the buuter-bar. The said pin swings freely and back ard on a pin, g, which goes through the lever and a tenon, l, formed on the upper part of the said pin, and extending through a slot or mortise, t', made down through the'lever.

The mortise and tenon are so made as to cause the pin, when forced back to its rearmost position while the lever is resting on the bunter-bar, to stand at an acute angle with respect to the lever, or in manner as represented by dotted lines at O', in Fig. 3.

The coupling-link D, while passing or being forced into the bunterbar will press the pin O backward into the inclined position shown at O. After having reached such a position, the pin, by abutting against the rear end of the mortise t', will serve as a cam or inclined plane against which the link will operate in such a manner as to force both the pin C and the lever B upward. They will continue to so rise until the curved end of the link may have passed sufciently in rear of the pin to enable such pin to enter the link, which having taken place the pin will immediately fall or be driven downward through the link by the reacting power of the springf, and will thus couple the link to the bunter-bar.

A staple, 7c, fixed in the lever B, is for the purpose ot enabling a tripping-rope to be attached to the lever. By pulling such rope upward the lever may be elevated so as to draw the piu out of the link, in order to uncouple the two.

The lever end of the pin is made conical, as shown in Fig. 3. By so making the pin its rise over and on the link will be facilitated. The object of making the fulcrum-pin passage d, ofthe lever B, an elongated slot instead ot' a cylindrical hole is to enable the lever not only to turn on its fulcruln but to slide upward therein under the pressure of the link against the pendulous pin O. The sliding oi' the lever on its i'ulcrum aids in raising the pin O relatively to the link, and thus enables a shorter pin to be used and a less angular movement ot' the lever requisite than would be the case were the hole in the lever Jfor the reception of the fulcruin-pin to be a cylindrical one having the same diameter as the fulcrum-pin. The slot in the lever also enables the strain of the draft-link on the pin O to draw such pin closely against the front end or part, l, ot' the vertical slot or passage made through the bunterbar, and thus relieve the fulcruin-pin cfroni the pressure occasioned by dral't on the link.

I do not herein claim the combination of a curved pin with the tripping-lever and the recessed bunter-bar, the whole being as represented in Letters Patent No. 45,733, granted to me ou the 3d day of January, A. D. 1865. Nor do I claim the improvement or car-coupling which constitutes the subject ot' the United States Patent No. 44,484.

What I claim as my improvement is- The car-coupling as made, not only with the pendulous pin C, combined with or applied to the lever B, and so as to operate there with, in manner and under pressure of the link, substantially as described, but as having the slot d in the said lever to enable the latter to slide upward on its fulcruin under circumstances and for the objects as hereinbefore explained.
